Title: Magnetic field measurement device
Inventor: YAMAZAKI KENICHI
IPC: G01R33/02
Filed: 1997-09-02
Abstract: PROBLEM TO BE SOLVED: To simultaneously measure the magnetic flux density of the magnetic field of triaxial direction components orthogonal to each other and to provide the synthetic value of the magnetic density and the values of the long axis and short axis of an elliptic magnetic field from the measured values. SOLUTION: This magnetic field measurement device 1 is composed of sensors 3a, 3b and 3c, a processing part 5 and a display part 7. The sensors 3a, 3b and 3c can detect the magnetic field of the triaxial direction components orthogonal to each other. The processing part 5 computes the measured values of the triaxial direction components obtained by passing measurement signals from the sensors 3a-3c through the filter of a prescribed band and the synthetic value of the magnetic flux density and the values of the long axis and short axis of the elliptic magnetic field, based on the measured values in the case of commercial frequency measurement, or computes the measured values of the triaxial direction components obtained without passing them through the filter and the synthetic value of the magnetic flux density based on the measured values in the case of wide band measurement.  The display part 7 displays the result of an arithmetic processing in the processing part 5.

Title: Thin film magnetic head and its manufacture
Inventor: WADA KUMIKO
IPC: G11B5/31
Filed: 1986-10-06
Abstract: PURPOSE:To generate no magnetic flux saturation of a core part, and also, to improve the working accuracy of a track width by forming a second magnetic layer being narrower than the track width, on a first magnetic layer which has been generated by working it to a prescribed track width dimension. CONSTITUTION:The first magnetic layer 13 is formed by a thin film thickness of an extent that a tapered angle is scarcely generated, even if a fine working is executed by using ion milling etching. Accordingly, a track width lT is controlled with high dimension accuracy by this first magnetic layer 13. However, since the film thickness is thin by only this first magnetic layer 13, there is the possibility that the magnetic flux is saturated in the core part especially, therefore, the second magnetic layer 14 whose width is narrower than that of the first magnetic layer 3, and also, whose film is thick is formed. In this case, the second magnetic layer 14 is formed more narrowly than the track width lT, therefore, the working accuracy of the second magnetic layer 14 exerts no influence on working of the track width. In this way, the working accuracy of the track width lT is raised, and also, a thin film magnetic head for generating no saturation of a magnetic flux can be realized.
